They do - Poland agreed to the same decarbonization targets and participation in the carbon market as the rest of the EU so it had to implement policies supporting them - chiefly in the form a solar power subsidy program. The program was more successful than the government anticipated and capacity ballooned so much that the grid needs modernization if it's to support more renewables. Also electricity usage per capita per year is like 25% lower than say in Germany or France, so emissions in absolute terms are lower than they might appear. There's a long way to go, but the country is on track to meet the goals set - partly because it's actually cheaper that way.
